Hunger Factor:
While Plenish do beginner, intermediate and advanced cleanse plans, there's no kidding anyone that juicing is tough. But for me this is the most satiating juice cleanse there is. Plus, what you will notice (if you usually suffer from hunger pangs between meals, as I do) is that while you will always be ready for your next juice, you'll never suffer from the shakes, headaches and light headedness that a sugar and stimulant loaded diet usually creates. It's hunger, if you like, in its purest form. Plus, as long as you leave an hour between juices, when you take your six drinks is up to you. Get past the first day and the hunger factor moves onto a home straight anyway.

Flavour Ranking:
Again, the best juice flavours I've tried - particularly considering that each bottle is bursting with mind and body boosting veg (the Sweet Sexy Green, which you'll have twice a day, has over two kilos of alkaline kale, spinach and broccoli in it). As for the Cashew Milk, which you drink before bed, I loved it so much I bought three more (you can find all their juices at Daylesford, Harvey Nichols, Planet Organic, Selfridges and Liberty) for the ensuing post-detox days.

Weight Loss:
4.5lbs in three days. Yes a lot of that is water, but I feel the difference, and whatever it was that fell off has now made room in my life for my 'skinny' jeans. My advice is to take advantage of the pre and post cleanse consultations with the brilliant in-house nutritionist Eve Kalinik (who has already put me on
chromium supplements
to help with sugar cravings and
Linwoods Flaxseed
to help clean up my system) if you want to keep up the good work once you've finished.

Skin Boosting:
One of the reasons I've done Plenish a few times now is because I love the way it clears up skin and eyes. On my second day I recieved two 'brighter skin' comments.

Energy Levels:
I am a seasoned juicer it has to be said, so I know what to expect. But even from the get go (I've done Plenish three times now) the Plenish cleanse programmes have always had the immediate effect of rebooting your energy. You'll never feel like you're running on empty either, partly because in-house nutritionists have tweaked each blend to balance your energy levels; the Sweet Sexy Green contains high levels of vitamin B and folate to support immunity and fight fatigue, while the Mind Body Green blend uses vitamin B and folate to support psychological performance. Cutting out the baddies, and introducing your RDA of vitamins and minerals also means quality of sleep improves. If you're a gym bunny, just ease up on cardio and go for yoga or stretching classes if you must.

Logistical Ease:
The entire three day batch is delivered to your door the night before. Just remember to take enough bottles the following morning to get you through your working day.

Difficulty Rating:
The immediate change you feel is motivating in itself, but it is tough. It is also though, for the record, addictive.

Good For:
Tired, stressed out types who rely on coffee and chocolate and more of the same to get them through the day. Or anyone who can't seem to shift that elusive five pounds.

Hunger Factor:
The Detox Kitchen's portions are delicious and above all, generous. The day started off with a wholesome helping of granola or Bircher muesli, which certainly kept the mid-morning rumbles at bay. Lunch - often geared towards quinoa and lentils - was also ample. I did get peckish before my evening meal, but more likely because I'm used to grazing on sugary treats all afternoon.

Flavour Ranking:
The aubergine Thai green curry with a fillet of ginger salmon was tastier than anything I ever ate in Thailand, so much so that I tweeted them asking for the recipe. Evening meals were definitely a taste sensation - the king prawn and lentil dahl was also a highlight.

Weight Loss:
I lost 1lb and my stomach felt and looked flatter in the absence of wheat and sugar. I'm also prone to bloating and this didn't happen during my three-day feast.

Skin Boosting:
I think my skin looked a bit clearer, but that's as much as I noticed.

Energy Levels:
On the second day I suffered from a bad headache in the afternoon, which could have been my body crying out for caffeine and sugar - or equally just tired eyes desperate for a screen break. I felt sleepier earlier in the evenings and slept well, waking up before my alarm. I carried out a one-hour yoga class and my usual 35-minute swim and felt fine.

Logistical Ease:
This was so easy you'd have to be a fool to reach for the biscuit tin while undertaking a menu plan. Everything you need to eat for the day ahead, including mid-meal nibbles and a dose of lemon or mint for hot drinks, is included. On my day off from work I just took my lunch and juice out and about with me, stopping for a herbal tea. It couldn't be any more straightforward.

Difficulty Rating:
I was surprised to taste food that was consistently appetising despite being sugar and wheat-free, so aside from the odd sweet or chocolate craving, this lazy girl's approach to detoxing was a doddle.

Good For:
Food lovers and would-be detoxers who can't face the prospect of a week on liquids-only. I have zero willpower when it comes to sweet treats but stuck with it because I knew my body would thank me for it in the long run.

Hunger Factor:
While you'll feel lighter, and you might crave your fixes, you won't go hungry. However the breakfast (a moreish blend of porridge oats, shiso cress and shredded carrots on all three days) are light, so if you're used to a hearty meal first thing, prepare yourself. The evening meal - usually with a good sized portion of brown rice or soba noodles - will though leave you feeling nicely full, which helps lull you into a happy, well fed slumber.

Flavour Ranking:
Let's get this straight; you have to like fish, and lots of it. And if you do you'll enjoy every meal (bar breakfast) as each includes fish and seafood of a high quality, including scallop sashimi, fresh poached salmon and tuna. (Though there are plentiful salads full of avocado, endamame, spinach and wakame). But if you like Japanese food, and you like seafood you will love this - strong flavours and satiation are not the issue here, it's delicious.

Weight Loss:
2.5lbs, with a definite de-puffing effect from head to toe. However, this 1,500 calorie a day plan is more about a menu clean up, than a weight loss fix.

Feng Sushi cleanse, day 2

Skin Boosting:
Coming out of the sugar and alcohol onslaught of Christmas my skin definitely calmed down a little.

Logistical Ease:
With warm meals delivered twice a day anywhere in London - bang on time - it actually feels like luxury. The only thing to remember is bringing in your porridge for breakfast. Simple.

Difficulty Rating:
Depending on what your guilty pleasures are (if you're a sugar or caffeine addict there will be teething problems), this actually errs on the easy side.

Good For:
Stressed out city workers that have been living on too much sugar, alcohol and caffeine but don't want a menu clean up that is high on effort and low on flavour. Reminding yourself that you can eat quite happily, quite healthily, it serves as a real red flag to all the nasties you eat without thinking.

Hunger Factor:
Those keen on breakfast will find the two small smoothies hard going in the morning. Though each daily blend was delicious I had to supplement my two drinks with nuts. Lunch and dinner were both ample portions, with the evening meal including a main event (eg. quiche or pizza) plus a salad.

Flavour ranking:
The juices and smoothies are tastier than anything you can buy in the supermarket, while salad enthusiasts will find the innovative parsnip cous cous and butternut pasta a welcome change from the norm. And who knew you could make a mushroom burger (plus bun) out of solely raw food?

Weight Loss:
1lb, but I would predict more for those who will find the abundance of vegetables and no meat an utter shock from their normal diets.

Skin Boosting:
Clearer skin due to the increase in fluids and absence of sugar.

Energy Levels:
I noticed I was a lot more tired than usual in the evenings, but this was probably due to the lack of sugary treats in the afternoon. I found I also woke up needing the toilet more due to the amount of fluid I was taking on (herbal teas and juices as well as more water). Although I didn't exercise for the period I think it would have been fine.

Logistical Ease:
Very easy. All the meals come early in the morning so you can have them delivered to work or home at your convenience.

Difficulty Rating:
I would definitely do it again - if just for the innovative menu ideas and freshness of the food.

Great For:
People who are flirting with vegetarianism or a vegan diet.

The Pure Package

The Pure Package,from £32.95 per day (purchased in bundles of 10, 30 or 90 days). Tested by Belinda White

Hunger Factor:
I always like to 'front load' my day, preferring a big breakfast and a smaller evening meal. But this diet reversed that, with a smaller breakfast and a bigger lunch and dinner. Therefore my hunger pangs were at their peak mid-morning meaning that all my snacks were gone well before lunch. I was worried that would lead to being hungry all afternoon and evening, but not so! Both lunch and dinner were so filling that the rest of the day was a breeze.

Flavour ranking:
Every meal was nicer than anything I ever cook myself - great variety and delicious.

Weight Loss:
1lb, which doesn't sound much, but for just three days of easy dieting is definitely a solid start.

Skin Boosting:
I didn't notice any difference in my skin.

Energy Levels:
My energy levels were largely unchanged. I never felt particularly lethargic, or bursting with energy, but my body is pretty stubborn like that at the best of times.

Logistical Ease:
Couldn't have been easier. The Pure Package fairy would come in the dead of night and leave my day's delivery on my recycling bin. My biggest concern was whether my local foxes would beat me to it!

Difficulty Rating:
I honestly felt I ate more than usual, and better than usual. I only craved sweet treats because I knew I wasn't allowed them, not because I was hungry.
